I will extend then. Will the BTC arrive sooner or later? What is the worst case scenario?

Unfortunately, this is something out of ChipMixer's control. Fees are terribly high now, 750 sat/byte is needed for a fast confirmation, and anything smaller is just ignored by the miners.
That means a small transaction with 1 input and 1 output requires almost 0.002BTC fee.
I expect fees to get lower again at some point, but I don't expect it to happen any time soon. Maybe next Sunday again? Either way, just keep extending your session every day until it's confirmed.
